y PENNSYLVANIA, ASSIGNOR 'T0 THE RUST ENGI- NEERING' COMPANY, OF PITTSBURGH, TENNSYLVANIA,

A CORPORATION 0F DELA- Application led December 26, 1925. vSerial No. 77,773.

This invention relates to wall structures and, while not limited thereto, relates 'm particularly and the like, of the compound type,

an air space between the wall parts and provided with a novel form of4 anchor or inter-'- lock for connecting the wall parts.

One object of'this invention is to provide i 'a compound Wall of the class described having a novel form of anchor or interlock which will permit lateral and vertical movement ofi one of the wall parts relative to the other@ Another Objectis to provide a novel form of anchor unit or brick particularly adapted to form the novel anchor or interlock of this invention.

A further obiect is to provide a Wall of the type! described having the novel, design, construction and combination of parts hereinafter described and illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a perspective view of a wall embodying my invention.-

Figure a2 is a similar view showing a modiied embodiment of my invention. v

Figures 3, 4, 5, 6, and 7 are enlarged detail views of the anchor blocks or bricks.

Figure 8 vis a perspective view of a wall embodying a -still further modified form of my invention.

Figures 9 and lO'are detail views illustrating the means for tying the anchor blocks to the .buckstays Figure 11 is a sectional view showing misalined anchor blocks to illustrate the function of the filleted or rounded edges.

Referring more particularly to the drawings, the numerals 2 and 3 designate the wall parts which are spaced apart to form a vertically extending air space 4 therebetween. rIhe walls are composed of bricks or blocks 5 laid up in rows or courses in the usual manner, and provided with 'expansion joints 5",

At spaced intervals in the wall structure I have provided anchorsA composed of cooperating anchor blocks or units laid upl in each of the wall parts 2 and 3 and interlocked with each other to tie the wall parts 5o together. The anchors A are spaced vertically and horizontally and are staggered vertically so as not to close the air space 4.

' In Figure 1 I have illustrated a wall construction having the anchors A'composed of units or blocks B all of the same design.

of the ordinary bricks or blocks of 4which the wall is composed, and comprise a vbody portion 6 having. a tongue 7 projecting from one j end. The "tongue 7 is appreciably narrower i. than the body portion 6 so as to provide shoulders 8 at each side thereof. vThe side .walls of the tongue 7 are compoundly curved to form opposite concave portions 9 and opposite convex portions 10, thereby providing a narrow neck portion and enlarged outer head portion of the tongue. The radii of the convex portions 10 is less than the radii of the concave portions, so that when the tongues of the opposite units are interlocked and the convex portion of one tongue is opposite the concave portion of the other tongue an expansion space S will be formed, which will permit a limited lateral movement of the wall sections and also unequal expansion of the anchor units themselves Without fracture.

The anchor blocks B are ofi such size that the tongues 7 will project entirely within the air space 4 thus permitting free vertical movement o f one wall relative to the other while also permitting a limited lateral movement.

The length of the tongues 7 is such that when the forward face of the tongue of one block or'unit is engaged with the shoulders 8 of the opposite blocks the space between the side walls of the tongues will be equal on both sides. This feature facilitates the laying up of the blocks and'insures the equal spacing of the tongues 7.

If desired or necessary the blocks B in the outerwall may be provided with holes to receive the ends of anchor rods 14 which are bolted to buckstays 15 to tie the wall to the steel framework of a furnace.

In -Figure 2 I have shown a section of Wall in which the anchor A is composed of cooperating anchor blocks or units B and C. The units C, instead of having tongues, are provided With recesses 16 having a compoun of the anchors yA. composedof the units B and C is the same'as that described above,

to wall structures for funaces \I`he blocks B have a thickness equal to two avingV d curved side wall provided with -a concave except that the number of units forming the anchor is limited to three, while any number of the units B may b'e employed.

When desired or necessary two or more layers of the anchor units may be laid up, one on top of the other, to form the anchors A. In order t'o permit 'the free vvertical movement of the one wall part relative to the other, when this construction is used, the interlocking or abutting portions of the anchor blocks or units have their upper and lower ed es illeted or beveled, as at 20, so that if t e units should be slightly overlapped when laid up the illeted edgeswill engage when unequal vertical expansion of the wall parts occurs and by a Wedging action force the units into alinemcnt.

While I have shown my invent-ion as applied to outer furnace walls, it will be understood that it may be applied to any compound wall construction where unequal expansion may occur and, therefore, I do not wish to be limited to the specific embodiment shown and described since various modifications may be made without departing from the scope of my `invention as defined in the appended claims.

I claim:

1. In a furnace, an outer wall, an inneru wall spaced therefrom to provide an air space between said walls, each of said walls comprising a plurality of courses of structural units, and inter ocking means on certain of said units and located entirely between the planes of the adjacent faces of the inner and outer walls so as to lie entirely in said air space and permit relative vertical movement of said walls for at least the entire depth of said interlocking units.

2. In a furnace, an outer wallan innei wall spaced therefrom to. provide an air space between said walls, each of said walls comprising a plurality of courses of structural units, and interlocking means on cer tain of said units and located entirely between the planes of the adjacent faces of the inner and outer walls so as to lie entirely in said air space and said interlocking means being adapted to permit a relative vertical movement of said walls for at least the entire depth of said interlocking units andto permit a limited lateral movement of said walls.

relative vertical movement of said walls for at least the entire depth of said interlocking units.

4. In a furnace, an outer wall, an inner wall spaced therefrom` to provide an air,

.space between said walls, each of said walls comprising a plurality of courses of struc- :tural units, and interlocking tongues and recesses on certain of said units and located entirely between the planes of the adjacent faces of the inner and outer walls so as to lie entirely in said air spacejjand permit relative vertical movement of said walls, said tongues and recesses having cooperating convex and concave surfaces, the convex surfaces having greater radii than the concave surfaces.

5. As an article of manufacture, a structural unit comprising a body having a tongue projecting from the forward end thereof provided with a convex and a concave surface, the radii of the-convex surface being less than the radii of the concave surface.

6. As an article of manufacture, a structural unit comprising a bod having a `tongue projecting from the forward :end

thereof 'provided with convex and concave surfaces, the radii of the convex surfaces being less than the radii of the concave surfaces.

7 As an article of manufacture, a struc# tural unit comprising a body having a tongue `projecting from the forward end thereof provided with a convex and a concave surface, the radii of the convex surface being less than the -radii of the concave surface, theforward end of said body and said tongue having its top and bottom edges filleted.

In testimony whereof, I have hereunto signed my name.

GEORGE E. DIGNAN.
